Abstract:
An amplifier circuit. In one embodiment, the amplifier circuit includes an output stage and a gain stage. The gain stage includes first and second differential output terminals that may be coupled to first and second differential input terminals of the output stage. The gain stage includes a first feedback loop and a second feedback loop. First and second half-stages within the gain stage may be coupled to provide the second feedback loop. The first half-stage may be coupled to control a first output current at the first output terminal of the gain stage, while the second-half-stage may be coupled to control a second output current at the second output terminal of the gain stage.
